Today we relax on our panoramic Lake Achensee cruise, set against the imposing backdrop of the Karwendel Mountains, and take in the beautiful scenery from a different perspective. Often referred to as the Fjord of the Alps, this is the largest lake in the Tyrol, stretching for over 9 kilometres in length, and its famously turquoise hue makes for a memorable experience. Afterwards, we continue on to Rattenberg, the smallest town in Austria. Built in the shadow of Rat Mountain, the town has a long history of glass-blowing plus a picturesque well-preserved medieval centre and rows of brightly-painted townhouses. Take the chance to visit the magical world of glass - the famous Kissling Glass factory and show room, where you can watch glass blowers, engravers and painters at work.
